WARNING

This master branch contains the v2.x codebase for ZeroClipboard! For the v1.x codebase, see the 1.x-master branch instead.

ZeroClipboard

The ZeroClipboard library provides an easy way to copy text to the clipboard using an invisible Adobe Flash movie and a JavaScript interface. The "Zero" signifies that the library is invisible and the user interface is left entirely up to you.

This is achieved by automatically floating the invisible movie on top of a DOM element of your choice. Standard mouse events are even propagated out to your DOM element, so you can still have rollover and mousedown effects.

Development

Before submitting a pull request you'll need to validate, build, and test your code. Run the default grunt task in your terminal.

$ grunt

Testing

If you just want to run the tests, run grunt test.

$ grunt test

Limitations

User Interaction Required

Due to browser and Flash security restrictions, this clipboard injection can ONLY occur when
the user clicks on the invisible Flash movie. A simulated click event from JavaScript will not
suffice as this would enable clipboard poisoning.

Testing ZeroClipboard Locally

Support

This library is fully compatible with Flash Player 11.0.0 and above, which requires
that the clipboard copy operation be initiated by a user click event inside the
Flash movie. This is achieved by automatically floating the invisible movie on top
of a DOM element of your
choice. Standard mouse events are even propagated out to your DOM element, so you
can still have rollover and mousedown effects with just a little extra effort.

ZeroClipboard v2.x is expected to work in IE9+ and all of the evergreen browsers.
Although support for IE7 & IE8 was officially dropped in v2.0.0, it was actually
still technically supported through v2.0.2.
